I have a 33-2 with a walk-through Transom (I hear the last several off the line had these transoms). The vent for the diesel tank was never installed. I checked the tank fill, and does not appear to have a fitting to attach the vent hose to. I'd like to locate the vent the same way the factory did it. I've checked two other 33-2's in the club (a fin keel, and a Keel c/b), but they don't have my transom, and the chainplates for the backstay are farther outboard with my transom. If there's any other owner with the W/T transom, can you give me some guidance on where the vent is relative to the chainplate? Thanks
